The peaceful grounds of this Brooklyn oasis make it an ideal spot for a romantic midafternoon stroll. The Cranford Rose Garden and the gorgeous cherry trees flourish during the warmer months; you also can explore the serene Japanese Hill-and-Pond Garden, centered on a torii gateway and surrounded by maple and pine. The Steinhardt Conservatory includes a tropical orchid collection and an indoor desert.

Design touches like a modern chandelier and a distressed concrete wall speak to the seriousness of purpose at this stylish corner restaurant. The New American menu of small and large plates changes seasonally. If you just want a drink, this upscale neighborhood spot is as fine a setting for a meal as it is for a cocktail (try the James’ Revenge—rye, Cointreau, vermouth, bitters and blood orange).

Skip a standard dinner-and-drinks date in favor of this monthly late-night soiree at Kings County’s premier institution. The evening includes lectures, live music, performances, discussions and a cash bar. Each party takes inspiration from the exhibits on view or, on occasion, neighborhood events.

Stop by this intimate cocktail bar for a postprandial tipple. The interior—kitted out with white subway tiles, a copper-topped bar and dusky lighting—sets an appropriately romantic mood. The stylish leather banquettes are prime spots for you and your date to sip craft libations like the Puritan (gin, vermouth, yellow Chartreuse and orange bitters).
